In 7th the Wood Elves were pretty darn to catch, let alone beat. Also, their cavalry used to break ranks which made their wardancers and dryads pretty nasty.
Nowadays though...they don't

Dryads will eat your support troops alive, but get eaten by your heavies.
Terradons are absolute beasts vs WE. They can target anything they want, and fly anywhere they want. A big nuisance and a possible threat all around the board.
Chameleons are always good, just keep them out of CC as always. Harder to do against de woodies, but run!
Salamanders are also great, no partials help to flame anything that burns (like: trees!).
Saurii are good. They can pretty much match and most of the time beat anything the wood elves can throw at them. Only they will be chasing ghosts a lot of the time. Try to force the issue or funnel their troops into your spears! (or HW+S).
Try to stay out of the woods with your support troops. Your blocks can handle some beating, but your skinks most certainly cannot.
They have spells to deal damage to units in woods, and can move the woods themselves. Remember this when you are about to make a glorious cavalry charge...
They have good defensive magic, but our Slann should overpower them.
All in all, I think you should be able to beat them (most of the time).
Good luck!
