If I had to guess with Asuka, assuming she's not terribly eccentric (due to any wealth she potentially has), she probably keeps normal hobbies.
I assume at home she enjoys watching TV, Dueling Juudai for fun, and talking with him when they're both in a good mood. Maybe play some games with him.
Herself? Likely reading, exercise (I'm forced to consider she probably used to be a Gymnast/Dancer and then puberty hit her, hence her focus on Cyber Sporty cards, as I'd figure her figure would basically destroy the ability to compete in either.) like jogging, maybe boxing.
Considering her theme music from the show as well as her knowledge of ballet terms, and her ace monsters from the show? Probably also fond of listening to classical western music (while reading or doing teacher paperwork or any possible jogging).

And as a bonus: She probably knows French.
