When you sing air pushes against your vocal cords making them vibrate. When you yawn its your bodies way of getting more air. So what seems like is happening is when you are going for lower notes you are tightening and restricting your bodies air flow so you yawn in order to open that back up. Make sure you are keeping your chest cavity open, and you are drooping your belly when you sing.
