What to do after you are ahead top, get first tower and your team is behind?

I'm a mid diamond player, but I feel like one big skill I lack is I'm not very good with playing around my lead and especially because I play 1v9 champions like Jax and trynda. In most of my games, I win lane and secure first tower top, what I do after that is push the next wave and place a deep ward in the enemy jungle. But after that I'm clueless. If bot is behind, do I just walk to their lane and look to 3v2 to then take tower, or do I swap with them, maybe go mid and look to dive + take tower? I'm assuming this is very situational but in general what would the tip be?
