¿Qué haces?, or you could say ¿qué estás haciendo?. The first is literally "What do you?", but is normally translated as "what are you doing". The second is the real progressive tense, literally "what are you doing?". It is important to remember that the Spanish progressive is not used nearly as much as in English, and only applies to actions currently happening.
As an example, in English we would say "What are you doing tomorrow?". If you converted that to Spanish, you might think it would be "¿Qué estás haciendo mañana?", but that is incorrect grammar. You would need to say someting like "¿Qué haré mañana?" (future tense - What will you do tomorrow), or "¿Qué vas a hacer mañana?" (What are you going to do tomorrow?), or even "¿Qué haces mañana?" (present tense - what do you tomorrow?). The third example is not correct in English, but is completely acceptable in Spanish.

There are various ways to say "How are you doing?" in the Spanish language. Though the most formal way would be: "Como estas?" = "How are you doing?" "Como has estado?" = "How have you been doing?" :)
