The basic problem is that your are hucking the flip with no conscious plan on actually landing. Whenever you do that (even on a straight air)... your body unconsciously automatically "opens up" (i.e. chest facing the downhill) - which is natural ... except for the fact that snowboarders need to land "sideways."
You should really practice doing backflips on a trampoline and learn to spot the landing and not freak out and try to twist your board to get the closer foot (often the wrong foot) under you. For a backflip, when you see the ground (when you are basically a little past halfway in the flip and completely inverted), you need to consciously pull your legs under you and get ready to land.
