Past Tense of Lie
English has two different verbs spelled “lie.” The intransitive position/recline verb follows lie → lay → lain, while the falsehood verb follows lie → lied → lied. Keep both paradigms separate, and also keep the transitive verb “lay” (“put/place”) distinct from the recline verb “lie.”
The past tense of “lie” depends on meaning: for reclining or being situated, use “lay” (past participle “lain”); for telling an untruth, use “lied” (past participle “lied”).

Quick tests
Verb-form test
Which verb do you mean: “lie” = recline/be situated, or “lie” = tell an untruth?
If yes: For recline, use lay in simple past and lain as the participle; for falsehood, use lied in both past roles.
If no: If you mean put or place something, you may instead need the separate verb “lay,” whose past is “laid.”
Caveat: Sense comes first. A single “past tense of lie” answer without this split is incomplete.
Examples
I lay on the sofa for an hour yesterday.
“Lay” is the simple past of “lie” meaning recline.
She had lain awake for most of the night.
“Lain” is the past participle of the recline/position verb.
He lied about the delivery date.
“Lied” is the simple past of “lie” meaning tell an untruth.
They had lied to us before.
“Lied” is also the past participle of the falsehood verb.
Further guidance
Core difference
First identify the meaning. Use “lay” for simple past of the position/recline verb and “lain” for its participle; use “lied” for both past roles of the falsehood verb.
Fast Test
If the sentence means recline/be situated, choose between lay and lain by grammatical role. If it means tell an untruth, use lied.
Usage Boundary
Do not collapse the two verbs spelled “lie.” Also do not confuse past “lay” of recline-lie with the separate transitive verb “lay,” whose past is “laid.”
