There are two basic rules for converting sentences from Active Voice into Passive Voice, which are common for all tenses :---

1) The places of subject and object will be interchanged in the sentence.

Active voice :- Sub. + have/has + P.P.form of verb + obj.

Passive voice:- Sub.(obj.) + have been/has been + P.P. form of verb + prepositional by + obj.(Sub.)

2) Only 3rd form of the verb or Past Participle (e.g. written) will be used as a main verb in Passive Voice.

→ Passive :- How had that been done yesterday ?
