Well after looking at your games collection i must recommend Final Fantasy 3 and 4 and Tactics A2. You may also want to look into Fire Emblem: Shadow Dragon, and the Advance Wars games may pique your interest as Soleron suggested. You've got Zelda: Phantom Hourglass, if you liked it you may want to take a shot at The World Ends With You, which also heavily uses the touch screen.
I must also stress the recommendation of the Dragon Quest games, they're both very good. Castlevania is worth a go as well, they're not full on RPG's but better than most on the DS. And you might like Mario & Luigi: Partners in Time, you may be able to complete it in time to get hyped for the upcoming Mario & Luigi RPG 3!!!
How technical is your game?
