Well, I guess it would depend on what spells you want to cast, if you want to have starting bonuses in those schools, if you want an additional starting spell, any unique racial powers, and so on. Pure mage (No weapons), Spellsword (Light Armor & Weapons),or Battlemage (Heavy Armor, maybe a shield, casting spells)?
An Altmer is inherently seen as an asshole, because of the Thalmor, and their general appearance. Plus, this races is a good starting point for most spell casters due to all of their bonuses are in the Mage skills.
Bretons are the second best Mage choice, as they have the second highest amount of starting bonuses in the Mage skills.
A Nord would be an option, because of their inherent fear/hatred of magic, as it is usually associated with the hated elves. Maybe a daughter that hates her parents, so she runs off to be a mage, to spite her family.
Khajiit would be another option, because like Nords, they have no starting racial bonuses towards spells, so you could infer another race that looks down on spell casting.
Bosmers are the only other race without any bonuses towards Mage skills. Orcs only have the bonus in Enchanting.
Personally, I would go with an Altmer, who was tossed out of the Thalmor after failing to assassinate Ulfric, which happened when she was caught by the Imperials took her, along with the rest of the criminals in the sting that captured Ulfric, to be beheaded at Helgen. Play her as hating Ulfric, because he got her caught, and hating the Thalmor for expelling her for failing to kill Ulfric. She might side with the Imperials, to get her revenge on Ulfric, pursuing the Dragonborn questline to infiltrate the Thalmor Embassy, to eliminate them entirely, and then going after Giants & Mammoths just because.
