For Udyr I like to start at blue buff for the mana regen so I can spam stances between turtle and tiger form. Then I work my way to wolves, wraiths, golem, then back to red buff. Now is the time where I like to do my 1st gank, so head bot for blue team, or top if your purple team. Recall for the 1st time this game to get boots, and madreds if you have enough. Go back through the motions again, wolves, wraiths, golems. By this point blue should be spawning again soon so grab that and head to top/bot (the opposite of which side you wen before.) Continue doing this pattern throwing in more ganks (since you clear jungle faster) until you get into late game phase.

At the end you can fill out your build with force of nature if they have a lot of AP, or thorn mail for AD, if your doing well however you might want to build guardian angel to make sure you are not dieing.
