Lightning can be used as a noun (bolt of lightning) or an adjective (lightning fast). It is not a verb, so it does not have a past tense form.
"Lightning" is a noun. Sometimes people try to use it as an adjective to mean "fast" (ex, "with lightning speed") but it really should be used as "like lighting" or "lightning-fast" or so on.
