'Que esta haciendo' = 'What are you (formal)/is he/she/it doing?'
You would respond by telling what you are/he/she/it is doing.
Clearly, this could be so many things, it is impossible to give a complete answer.
But depending on the relevant verb, and person:
In response to 'you', would reply
'estoy....' ( I am....) + the present participle of the relevant verb, e.g.
(from 'pensar', to think) '....pensando'; (from 'dormir', to sleep) '....durmiendo', etc.
In response to 'he/she/it',
'esta....' (accent on final 'a' + present participle of relevant verb, e.g.
'....jugando' (playing), '....comiendo' (eating), 'escribiendo....' (writing), etc.
