You could say "Suki deshoo" which is sort of like "You probably like me, don't you?". You could also be a little sarcastic and say " Zenzen suki ja nai desu, ne" which is "You don't like me at all, do you?" but if you say it the right way i'm sure they'll get it. It's not really easy to make a positive statement in a teasing way in Japanese, saying something that implies the opposite but doesn't really mean it is much easier and this is where the "teasing" comes in.
