Try staying down and through the shot without lifting up at impact.
Try keeping the grip pressure very light to give the wrists a chance to hinge
Try moving the ball position so you are turning behind it and staying behind it at impact
Try getting a little bigger shoulder turn going back
Try shifting your weight to the right foot going back and to the left foot through impact
Try getting or making an Inside Approach or stick an old shaft in the ground over your ball so you have to hit under it
Try placing a head cover along the outside of your ball pointing to right field so you swing along that line coming through without hitting the cover
Try using a stronger grip ie, left hand see 3 knuckles and right hand knuckles facing the ground; when you hook, you can move the right hand more so the palm is facing the target
Just a few things to try, let me know which if any work.
