1) check out the campaign ideas link in my sig- hundreds of ideas from fellow ENWorlders in there that are essentially pret a yoinker.
2) have some NPC or group of NPCS- such as town criers- that drop all kinds of plot hooks in their ordinary course of business.
3) as you run the campaign, listen to your players' table talk about the campaign. They'll be discussing things they think about the world and sometimes, what they wish would happen. And you go and recycle that into the above-mentioned NPCs banter. Your players will think they're reading your mind, while in reality, you're robbing them blind. This will also reduce your burden of trying to come up with plots on the fly because instead of just your mind at work, you're putting theirs to work as well.
