The name Asaiah in Hebrew letters is עשיה. Below: how its number adds up, which page of the Torah it falls on and what verse stands there. Everything is computed, nothing is guessed.
עשיה
In short
Your name in Hebrew letters is עשיה. A Tanakh name: three or four Israelites (first in 2 Kings 22:12; 8 mentions in the Tanakh). Meaning, per Strong’s dictionary (1890): “God has made”. Adding up the numbers of its letters gives 385 — the same as the Torah word שפה, “lip, language”. That number points to Torah page 31 of 354 — in the portion Vayera. What that portion is about: Three visitors at Abraham's tent; the plea for Sodom; the birth of Isaac; the binding of Isaac on Mount Moriah. The verse that begins with the first letter of your name and ends with the last is Genesis 31:52. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Asaiah” — this exact spelling is what was calculated: עשיה. A name from the Tanakh — its Tanakh spelling is used. If your name is spelled differently, correct the Hebrew spelling and the report is recomputed.
Adding up the letters of the name עשיה gives 385.
385
The number 385 is the Torah word שפה — «lip, language» (Genesis 11:1).
And G-d said unto Abraham: 'Let it not be grievous in thy sight because of the lad, and because of thy bondwoman; in all that Sarah saith unto thee, hearken unto her voice; for in Isaac shall seed be called to thee.
This is from the portion Vayera. What it is about: Three visitors at Abraham's tent; the plea for Sodom; the birth of Isaac; the binding of Isaac on Mount Moriah.
Other ways of counting
The tradition counts the same name in several ways. The main one is above: each letter is its number. The other eight are old and checkable too; each gives its own number, and many of them have a Torah word with the same number.
Final letters as 500–900 (mispar gadol) — 385. A Torah word with the same number is שפה — “lip, language” (Genesis 11:1).
Reduced, each letter to one digit (mispar katan) — 16. A Torah word with the same number is אחז — “to seize” (Genesis 22:13).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 52. A Torah word with the same number is בן — “son” (Genesis 3:16).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1490.
Squares of the letter values (mispar perati) — 95025.
Building: the sum grows with each letter (mispar bone’eh) — 1205.
The letters that come out are זבמצ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 139. A Torah word with the same number is לקט — “to gather” (Genesis 31:46).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 516. A Torah word with the same number is גרגשי — “Girgashite” (Genesis 10:16).
The number 385 appears in the classical books 40 times across 18 works. The earliest mention is בעל הטורים על התורה (~1300).

For an engraving, a sign or a tattoo, show the spelling to someone who reads Hebrew: transliterating a name is a choice, not the only option.
The name עשיה does not stand as a separate word in the Torah, but appears 1 time with prefixes — first in Numbers 28:6.
The verse of your name
There is a custom: at the end of the prayer one says a Torah verse that begins with the first letter of one's name and ends with its last. For עשיה these are ע and ה. The Pentateuch has 17 such verses. The first of them is Genesis 31:52:
עד הגל הזה ועדה המצבה אם אני לא אעבר אליך את הגל הזה ואם אתה לא תעבר אלי את הגל הזה ואת המצבה הזאת לרעה
This is from the portion Vayetzei. What it is about: The dream of the ladder to heaven; Jacob with Laban: Leah and Rachel; eleven sons are born; the return.
«And G-d said unto Abraham: 'Let it not be grievous in thy sight because of the lad, and because of thy bondwoman; in all that Sarah saith unto thee, hearken unto her voice; for in Isaac shall seed be called to thee.»
Each Hebrew letter has a number; a word's number is their sum (alef 1 … tav 400). The page is the remainder modulo 354: the Torah divided into 354 pages of 861 letters, as the lunar year has 354 days. Everything can be checked by hand.
