Skying drives is one of the most frustrating shots in golf. Try moving the tee further back in your stance, teeing lower and finally, closing the clubface to reduce loft. Remember to aim a bit more to the right if doing so. This advice is also useful when playing into a strong wind.
To achieve a lower trajectory with your driver, you will need to have a flatter swing arc just before impact with the ball. Take the club face back only half way on a flatter backswing and then bring the clubface through to the ball.
You are probably coming over the top so the club is coming into the ball very steep. Try to shallow out your path and keep pulling the grip through impact.
There are several things that you can do to get a lower trajectory. First, try to position the ball with it at the very front of your stance. You can even try it off the front of your foot. Also, tee the ball lower.
Hitting a ball high is generally because you are hitting down on the ball. Practicing taking the club away low and slow, getting a good shoulder turn, before hitting.
You are most likely holding the club with to tight and high of a grip which is causing the face to be at a steep angle when making contact with the ball. Lower the angle and the trajectory should lower as well.
Do you balloon your shot for only the driver or other clubs? If it's just the driver consider a less lofted club. If it's other clubs, consider your swing mechanics.
Tee the ball lower and move it closer the middle of your stance. This will cause you to make impact lower on the face of the driver, reducing the trajectory.
