Good question! This may sound weird, but ...
Believe it or not, you're probably better off vaulting just as your are ... without focussing your eyes on ANYTHING. Just let them do what comes natually. Don't try to FORCE them to do anything that's not "natural".
REMEMBERING what happened between takeoff and pole release is a cognitive skill that has nothing to do with the optical skill of SEEING what you're doing.
This memory comes from the sound and the feel of your vault ... as well as what it "looked like". It might help to think of this as the RHYTHM of your vault.
So instead of worrying about where your EYES should focus, focus your BRAIN on how the vault FEELS, using your 3 primary senses (sight, sound, and touch). This will give you the full "picture" in your mind's eye ... so to speak.
Biologically (and I say this from my experience as a vaulter - not a scientist - so if there's any experts in this field, please correct me if I'm wrong), the answer to your question is actually that your TIMING and BALANCE "on the pole" and "in the air" are probably the most important FEELINGS. As you know, timing is a function of the brain, and balance is a function of the inner ear.
Imagine your vault in slo-mo. As you're swinging up and over the bar, on each "frame" of your vault, your inner ear tells your brain ... and your brain tells your muscles ... "a little to the left" or "a little to the right", or "get back a little more" or "OK, you're reaching the peak of your vault now, so it's time to drop your legs and drape your arms over the bar" ... and so on.
Hint: When you stand at the end of the runway, preparing to vault, focus on one particular aspect of your vault ... preferably a technical weakness that you're trying to improve.
Then fire down the runway, and when you takeoff, continue to focus on that one aspect. When you land in the pit, ask yourself "OK, what just happened?" and "Was that ... [vault part] ... better that time?".
Continue your post-vault analysis as you leave the pit, grab your pole, and return to the spot where you'll be waiting for your next vault. Perhaps chat with your coach or a buddy about your last vault. Ask them what they "saw", and tell them what you "saw" in your mind's eye. DISCUSS it. If you don't have the right words to express "what just happened", your coach or buddy will, and you'll pick it up ... sooner or later.
The more you do this, the more you'll FEEL how your vaults were (good or bad), and the more self-analytical and self-aware you'll be about what went right and what went wrong.

Absolutely! That's how I suggest you can improve your self-awareness!
