If at address you can see your left shoulder, you are aligned right; if you can see your right shoulder, you are aligned left.
One thing I do, standing behind the ball back of it 8-10 feet--pick a spot 6"to 1 foot in front of the ball lined up to where you want your ball to go, walk up to your address position keeping your eye on that spot and just take the stance, it works everytime to keep you lined up.
