Jungle and what to do with leads

Ok so I main Kha'zix and I (although I probably shouldn't, but I still do) take all the kills when I gank, due to not actually trusting in my team mate to actually acquire the kill due to past experiences. So sometimes I get ahead in gold, kills and farm, in comparison to the enemy jungler, but I don't really know what to do when this happens. I mean I continue to gank and deprive the enemy jungler of their jungle camps but I just don't know what to do when I'm ahead as a Kha'Zix in jungle, or rather as a Jungler in general (though I normally only get ahead when I play Kha'Zix). Also I believe that my jungling skills in general need A Lot of improvement when it comes to:

1. Clears 2. Ganks (When to gank) 3. Engaging 4. Heroic Monsters -> Dragon and Baron 5. Warding 6. Positioning

If you could either comment what to do better, or post a link to a video that you believe would actually be beneficial for my learning it would be greatly appreciated.
