-Always keep an eye on your passive and try to refresh it when possible by quickly detaching, autoattacking and reattaching. But never detach during a fight when your W is on cooldown! The right usage of her passive is what separates the good from the bad Yuumi players. It can determine the outcome of a fight. Also during laning phase it helps you to keep your mana up.
-Q is great to harass your laning opponents or to chase fleeing enemies. While attached to an ally you can control its path.
-Try to use your E only when someone is really low to maximize its healing output and to surprise enemies with the sudden burst heal.
-While using your ultimate you can still use your W and E, so you can still heal your allies or reposition yourself.

Yuumi is great in engaging fights, just hop on to a frontliner / tank and help him initiate a fight with your ultimate. Refreshing your passive shield during teamfights is pretty important but be careful when doing it since Yuumi is extremely squishy.
