Transfer more weight to your back (the uphill) foot and play the ball a bit more forward in your stance, as your swing will bottom out later.
Uphill Lie
Transfer more weight to your front (again the uphill) foot and play the ball a bit further back in your stance.
Ball Above Feet
These shots tend to draw. Open the clubface a little and balance your weight towards the toes of your feet.
Ball Below Feet
These shots tend to cut. Close the clubface a little and balance your weight towards the heels of your feet.
