There aren’t many race choices available for a druid; you either go Tauren for Horde faction or Night Elf for Alliance side. Worgen and Troll are coming later after the Cataclysm updates. For now, Night Elf is still the most popular race for a Druid (that's the orginial race in the story anyway), so here are a few Night Elf Druid leveling guide tips:

1. Select more suitable tree for leveling
While I wil not against you going Balance and be a spellcaster, the Feral Combat tree with several points in Restoration is the most advisable spec for fast leveling. You'll be able to tank (to certain degree), burst decent damage, and can heal yourself. This is a perfect skill combination for solo leveling.

Of course, you can’t have your animal form from the beginning, so I recommend you utilize whatever you got to make life easier for you in the earlier level. Get these spells:
- Mark of the Wild: increase strength, agility, stamina, intellect, and resistance.
- Moonfire: enable you to kill faster.
- Thorns: damage the enemies if they hit you.
- Entangling Roots: another nice skill to conserve your life.
- Bear Form: the beginning of your life in Feral Combat.

I did mention that you should add a couple points into the Restoration tree, here are some of the most crucial to have:
- Improved Mark of the Wild: one of the greatest buffs in World of Warcraft.
- Naturalist: enhance your physical damage in all forms.
- Omen of Clarity (spell): provide you with chances to use your skills without using energy.

2. Complete all of the quests
Level 1-10 will be the easiest and quickest leveling in your whole life, so make sure you get and finish all of the quests. This is necessary because these quests will provide you with a lot of useful things along with gold and spells. Furthermore, they contain a number of important things that you will need later; so instead of saving a few minutes by skipping a quest and regret it later, it’s safer to do them all.

3. Don’t overlook your profession training
Quick start will make sure that your profession level keeps following your general level. Keep in mind that you can leveling some of these professions while killing monsters too, so they won’t slow down your leveling speed.

Your professions also will get you some extra cash from selling raw materials or making things. If you're just started, gatherer professions such as skinning and herbalism are great ideas.

You can make your leveling process easier by doing the tips above. All that left is knowing the right sequence to complete the quests in the shortest time possible while getting as much rewards as you can. For that, I suggest you get yourself a good Night Elf Druid Leveling Guide and get start immediately.
