the first time I played league I was obsessed with the jungle, (all though I was kinda still a noob) but now I'm playing ranked and my jungle game has gone down hill and I was hoping someone could help me with getting it up.
champs I mostly play in jg:
add me to help me jungle game :)
Most of those I suck at but here is one:
With Udyr, you absolutely cannot stop farming, even while ganking. It means that you have to know the game, to know when you can gank successfully and then path such that as you are walking back from the gank, you are also farming, either your jungle or the enemy jungle. You don't want to leave huge swaths of empty jungle just sitting there.
Farm, gank, keep track of objectives, take objectives. If you have jungle camps up you arn't farming hard enough. If your lanes are getting pushed in you don't have enough pressure.
The only champion I know very well in that pool is (I can sort of play some others). I mained him starting in early season four, but he's been nerfed into the ground. Runic was good when it was FOTM, but IMO sated devourer was what let you take over games, and that's gone. is quite weak right now. You might consider a replacement champion like 
if you want to play something similar.
You seem to have mixed interests when it comes to jungling. Once you feel confident, it's good to add some diversity to your pool, but while you're still uncertain, I'd pick a certain group of champions to learn.
Examples might be: Strong early gankers/duelists with a lot of pressure: 
Teamfight/AOE junglers (who usually gank bot very well at lvl 6 because of AOE CC/massive AOE damage) 
Farm and control junglers who clear quickly and split-push/control games: 
( doesn't have greatest waveclear but is an amazing duelest and has unrivaled sustain).
I hope I've helped. Good luck with jungling.
