1) What are you doing that makes you happy? [STRIKE]Or[/STRIKE]
[STRIKE]What do you do that makes you happy? [/STRIKE] See new #6.

2) What do you feel happy doing?

3) Doing what makes you happy?

4) What does doing makes you happy?

5) When do you feel happy?

6) What do you do that makes you happy?

1 doesn't work because the present continuous refers to what you are doing right now.
2 is grammatically correct but would lead to the reply "Travelling with my family".
3 is colloquially OK but I don't recommend that learners use it.
4 is ungrammatical.
5 is the best choice because it uses "when" and "feel happy", both of which appear in the reply.
6 should have been presented as a separate option, not included in 1.
