I like to use skill-capped.
In general though, after the gank you want to do two things, check your and your laner's HP bars and look at the state of the lane. If either of you are below 50% HP, especially against anyone who can roam over and has high kill pressure, just back. You got a gank off, probably a kill, good job. If you or both of you are high enough HP though, you need to decide if you want to push the lane or freeze the lane. Here is a guide on freezing lane, and if a freeze is not optimal for the situation, you should shove it up to tower. If you have a GIGANTIC minion wave, or if your laner starts hitting them, kill the next wave that comes to you under tower. Otherwise, just ignore them while you whack the tower. This will cause the lane to bounce back towards your laner, setting up you and your laner for more power plays (see the NSFW camping guide). Killing the next minion wave under the enemy tower's will cause a complete reset, which is good for very specific matchups
but it's really not optimal so avoid if you can. What you do after all that is champion and route specific though.
Instead of Ganking or Objectives, you should really think Ganking and Objectives. With that said however, let's say you see a laner or the Jungler roam over and gank the opposite side of the map, do you gank, do you solo the Dragon/Herald, or do you hold/shove the nearest lane? Once again, this is champion specific, but these are the options you should be weighing in your mind.
After all that, you transition into the midgame like so: https://www.youtube.com/watch?v=HQvoWcH37O4
And, well, that's your Jungling Guide.
