You should have a few options, depending on what you have already completed...

1. There are 5 or so quests for the Deadmines that are all for levels 15 - 20 or so.
2. There are two or three quests in Duskwood as mentioned - killing spiders west of raven hill and killing wolves north of the alliance town.
3. Wetlands quests start around level 20 or maybe a little higher.
4. There are three elite quests in Loch Modan to kill ogres, also several timed kill tasks based out of the Farstrider lodge (these can be easily overlooked). Also the series that starts at the dam in the same zone. But you may have completed all these already since they are for level 15+.
5. Head out to the elven lands. There are quests for southern Darkshore and also Ashenvale. I forget exactly when you switch from Darkshore to Ashenvale though. If you are on a pvp server, don't bother with Ashenvale, you'll spend more time corpse running than adventuring.

Hopefully this helps a little.
