What is the past tense of 완벽하다?

완벽했어요 in everyday polite speech, 완벽했습니다 formally. It is built from the 아/어 form 완벽하여 plus ㅆ, which is why an irregular stem shows its irregularity here.

Is 완벽하다 irregular?

Yes — it is 여 irregular (여 불규칙). 하다 and every verb built on it: 하다 → 하여 → 해요. That is why the stem looks different in 완벽하여 and 완벽하니 but unchanged in 완벽합니다.
