Basically establish a jab to the point that you could feint with them and hope your hook is good enough and your leg speed good enough to close the distance with it. You could also feint with the right shoulder to make it look like it's going to be a lead right, which actually puts your left shoulder a little more forward and closer to land without having to leap towards. Floyd and Martinez (whos a southpaw, but still same type of thing) do this.
Overall there's a lot of good tips here, but a lot also depends on how competent you are.
