Recall timings with ignite top

So these are the situations I run into often enough to wonder if I'm doing the right thing:

1. I kill him or he dies to gank but his wave is just on the outskirts of my tower, and its pretty big. So if I were to leave that then it will push into my tower before I get back because enemy has tp and I don't have tp, so whatever advantage gained from getting a kill is lost(and then some) if I let him run minions into my turret at the beginning of the game for 30 seconds.

So I usually just stay in lane and he gets a teleport back, sometimes with an item advantage if it was late enough in lane phase. Best case I have to play very carefully and wait for my jungler to force him back or kill him so I can get my minions to his tower, or to some slight push toward me or a near freeze.

I think what SHOULD happen in this case is that enemy top laner pushes as much as they can and go for a dive on me. Then I would be punished hard for not having tp and not having pushed the wave earlier before the kill happened.

2. I kill somebody whom I don't want to give free lane farm to and they dont have tp, but the wave is in a slight push toward him. So if I just left that then I would return and be boned cuz I lose like 2 waves to my own minions and he gets a big fat juicy 2 1/2 waves just reaching his turret as he walks back. So was dying bad if he gets that hmmm....

So in this scenario, I stay and usually have to push 2 waves and lots of the time he will get back during the 2nd wave being cleared before it actually reaches his tower, and sometimes even kill me if im being too greedy.

Well, this is now a bad situation because if it doesnt actually make it all the way to his turret or he finds a way to make a freeze there, then phhhht.... lose xp and gold and possibly get zoned off if he has some priority due to the nature of the matchup, or if he just has advantage enough through levels.

But say he does get back and I still have the lane priority(which I should have like lvl 4 or 5 vs lvl 2 or 3 in this scenario) I can still push it in and even trade with him some before I recall, so it CAN be ok. After I can set the lane up to not trash me in xp(without dying for it), then i recall. When I return I have much better item than him so it is usually ok he got some free farm.

Of course, ideally you want to kill people under their own towers so you don't have to deal with this crap, but its not always the case that you can do that obviously lol...

Anyway, as some context, I'm usually playing teemo or pantheon and this is mainly an issue of recall between levels 1-5 so theres not incredible pushing power with either champ im playing at that stage in the game. Do you think I'm going about this right as far as recalls go? Too greedy?

I mean, clearly it's working against the people I'm playing against. But idk say im playing vs high elo players, i wonder what they would do to abuse the recalls im taking and if they're really correct recall strategies.
