The first thing you must remember is that you do not want to come off as a jerk. Teasing is all about playing with women. And they love this game!
When you tease her, do it in a very playful passion. I cannot give you a ton of advice on how to be playful since it varies with your personality. For some, smiling while teasing works, while for most others the use of microcalibration works.
Never say sorry
You make playfully make fun of her laugh, but put your arm around her at the same time.
