Udyr can start any route he was and clear his whole jungle before scuttles spawn.
if you're afraid the enemy might invade your jungle start from top and work your way down.

so the order you want to go is:
Red, rocks, chickens, wolves, gromp, blue, scuttle, gank what ever lanes are inbetween.
or
blue, gromp, wolves, chickens, red, rocks, scuttle, gank what ever lane is in between.

if not ganks were successful, go back down to where u started from and repeat the cycle of jungle monsters once more that should get u to level 5 and half, then call back for items. grab a sheen and two swords and go back the buff you started at it should be ready for the cycle once more.

rush triforce first and then pick up shoes. hopefully you got some kills and they become ready for you.

then build deadmans or force of nature depending on what damage you receive more, and then build the other one after it.

with shoes, triforce, deadman, and force of nature you should be the fastest and tankiest alive on the map, no one can get away from you and no once can catch you.

finish it up with 2 dmg items like bork and titanic or what ever item is needed to fight off that enemy type.

your awakening is what makes other playe poop themselves. but you have to be smart about it.
when using your q make sure the order is: q> attack> attack> awakened q> attack> attack. this should bring the enemy down to 25% of their health and then you can finish them off. that combo also should full stack lethal tempo so you can start the real fight.

when ganking turn on press R to active slow aura, the press E to run and oppenent and stun.

if the enemy has cc and casts it, counter it by using awakened E and running through their cc or slows.
