I'd say that would be 'Ben je geroepen?'. The verb 'worden' translates to 'to become' or 'being', so 'being' is really necessary in the translation. ;)
What's the context in which one would use the sentence "are you called" in English? Because that doesn't really strike me as something anyone would say. "Were you called", I understand, but "Are you called", I don't see why one would use that, since the present tense places it in the same realm as "are you being called".
I'm a native Dutch speaker, and was doing this for fun. And I came across this question, and I filled in 'Wordt jij gebeld?' And it came out as wrong. Even though a word gets a -t at the end of it if the subject is 'you'. Or am I just derping up and does it not get a -t in a question?
