Route it over your right. Your first stage should have multiple low pressure ports, so attach your short hose to the front right one and the long hose to the back right one. The short hose will come directly over your right shoulder and sit beneath your chin....your long hose will come down your right side, tuck under something like a can light or knife sheath (or you could even tuck it into your waist strap), up your left side, around your neck, and into your mouth.
I don't know if you're into the whole GUE thing, but
HERE is some very good information on equipment and configuration. There are some pictures that will show you exactly what I said, if it was confusing.
