One in caldera where you just get a single drake and deliver it. there is also another one there but it is a bit harder.

Someone mentioned 8 in grizzly hills. these are easy and can be done quickly

on the ship in icecrown there are a ton of daily quests. there is only one or two i don't do. also, there is 'assault by ground' and a quest where you have to jump robots up a mountain. doing all of these will put you at about 20 quests or so and should take an hour and a half to two hours to finish.

Just found a guide that may be helpful

This quest below can be completed just using your main toon. No need to have all toons pick up the items needed. Just learned that the other day!
1.Mount up and get out of the ship. Head South-Southeast to the Broken Front [68,62]. Once you've arrived here we're going to do two things:

-Look for Pile of Bones, Abandoned Armor, and Abandoned Helm's which are scattered all over the ground.

A couple of things on these quests below. Leave our Mark can be done easily if you put the sword on a button and bind it to a key. Have all your toons target the dead body and hit the button. 5 swords planted at once. Only need to kill 3 mobs. Stealthy taught me that. And the Vile Like Fire you can just mount up with one toon and cast fire over and over on the building right next to where you mount at. I think Stealthy taught me that one as well.
1.Mount up and head northwest to The Shadow Vault [43,24]. Sell your junk, but remember not to sell Vrykul Bones yet. Get the following quests at The Shadow Vault:

[80]Leave Our Mark
[80]Vile Like Fire!

Don't do [80]Intelligence Gathering from Death's rise. Sucks
