You have to practice. One tip I heard - and I try to practice is to go out and hit different returns. So I try to hit 'loopers' and then "lasers' off the same 'rally' ball.
This method will teach your body how to change your swing to achieve the results you want. The thing is your swing is dependent on the incoming ball. So its actually more complicated then this. For a high ball that you want to 'laser' you might swing on a nearly level plane or even slightly down.
The reason why pros strokes look so much more automatic is because of their superior footwork they often get in very good position so MOST of their strokes look similar. I think its backwards to think about trying to replicate your finish. If you take the same ball - and hit it such that it has the same kind of action - you will get the same kind of finish.
