Bend at the waist and you'll hit exactly where you're aiming, despite your elevation (assuming you're not shooting some extreme angle due to range or extreme height...like 40 feet up).

As to the original poster...being able to shoot well is one thing, knowing where to aim is another. As others have pointed out, aim for where you want the arrow to exit (behind the opposite leg is a good place) and extend that path through the vitals. That will tell you whether or not you can take a shot that both hits the vitals and passes through the deer.
