At the most basic level (i.e., the only one I know well), the two biggest factors in a successful lead turn are separation and timing. (Lead turn, of course, can be in any plane, and usually is actually in the vertical.)
Separation isn't something that you can unilaterally control, because the other guy is doing something, too. Most people seem to think that you need quite a bit of separation for a good lead turn, but it seemsto me to be rare that you can actually do this.
Timing is the one thing you have complete control over. I've seen the good pilots differing, in marked degrees, on when to begin your turn. Some think you should start your turn when relatively far away, so that you complete the turn in close proximity to the target. Others think you should delay your turn until you have nearly (or actually) passed the target, in order to get an opportunity to shoot him/her during the post-merge turn or climb. I used to be in the first group, but I think I've had better success with the second.
The point is that there really isn't any substitute for just getting out there and doing it. Timing, in particular, will be different when flying in, or against, different planes, and you won't know how until you've done it.
