It's tough. There aren't enough balanced skills to make a truly interesting character. But try my favorite build:
archery (no quick shot or ranger perks), alchemy, light armor, filler skills like pickpocketing
No sneak, no melee weapons. Head to the morthal swamp asap, gather all the deathbell you can find (there's like 100 nodes there), mix it with salt piles to brew slow poisons, and hotkey them. Use it on tough melee guys and kite. Brew other useful poisons such as lingering damage health to help your damage. Make sure to boost stamina because you will need it to kite the undead as they are immune to poison.
Basically, a kiting build. It's fun, but it can get a bit repetitive. If the game had trap-making or shouts with shorter cooldowns it would be perfect. Any magic you add to the build will make it OP, so that's out of the question.
