Hi there,
Just a couple of things.
First off, you're under when you take off and you lean back when coming into the take off. This will automatically put your hips out of position even before you leave the ground. In the grand scheme of things this also means that your swing will be slower and almost invariably start later.

The result of this will be that you cannot cover the pole in time and subsequently your position at the top end will not be ideal. You can't cover the pole and extend fast enough (because the swing is slow and late - because you're under). Also because of the slowed movement from the swing you get "stuck" under the pole rather than being able to cover it better.
And you extend out (flat over the bar) rather than up (into ideal trajectory and pike position) due to two reasons:
First because the pole is working faster than you because of the stuff mentioned above. Your swing, cover and extension happens later and slower than it should. The pole is already at the end of it's uncoiling when you begin to extend. You have to remember that the pole is changing angles as it is straightening. You need to take into account that in the later stages of the pole's uncoiling, your trajectory will be flattened especially if you are not in good position. This is why you need to work back to the pole rather than aiming just over the bar.
Secondly, you're still looking at the bar (I suspect). This means that your shoulders cannot go down. Keep in mind that the shoulders are the critical point at this point, where they are placed and what they are doing determines the placement of your hips and how you extend. At this part everybody usually talks about what the hips should do, but in fact the hips have a very easy job - just extend, there's not much to it. The hips will always do this job no matter what because it is a natural movement. In what direction they extend to is determined by the shoulders since the shoulders are the link between the body angle and the pole.

The thing I like to tell vaulters is that when you see your feet cover the pole, your shoulders need to go down. If you're extending or begin to extend and you can still see the bar then that's a big no-no.
So in conclusion:
Work on taking off a bit further out - this will fix A LOT of things but this takes a lot of work during the off season, plenty of comments on how to do it around in the forums
Work to cover the pole faster and to a greater degree - without cutting the take off short to try and swing earlier, this will be easier with a fixed take off
Work on getting the shoulders down once you cover the pole - it will change the trajectory of your top end drastically. This is probably the biggest "short term" gain you can get while it's still competition season so it's probably what I would focus on the most right now. That said, the earlier and more consistently you can get onto taking off further out the better your results will be.
Hope that helps!
