Pembahasan:

Tag questions are used to confirm a statement. It is really depends on the tenses used, but if the statement is positive, the tag question should be in negative or vice versa.
Pattern:
statement (+/-) , auxiliary verb (-/+) + S?

So, from the sentence above,
you and I are friends, aren't we?

(because the auxiliary verb used is 'are', so the tag question is aren't we (same as the subject)
