Past perfect:

The house had been cleaned before the guests arrived.The documents had been signed by the time the deadline passed.The cake had been eaten by the time I got to the party.The movie had been watched before it was returned to the rental store.The book had been read before it was lost.The report had been submitted before the meeting started.

Past present:

The package is being delivered by the courier.The dinner is being cooked by the chef.The car is being repaired by the mechanic.The window is being cleaned by the maid.The project is being completed by the team.The presentation is being prepared by the assistant.
