Early Attack
A lot of people don't build up a defense at the beginning of the game, they wait for the long run. You can easily defeat those people by sending in an early attack. About 12 Zealots at the beginning of a game would be more than enough to destroy an undefended camp, 12 zealots would also seriously harm a rusher but not always destroy the rusher.

Scouts are the Key
If your early game attack doesn't kill your enemy totally, later in the game you should build up lots of scouts. Scouts are VERY powerful when in large numbers. But you have to accompany them with a couple observers to detect those annoying wraiths.
