I would suggest a male redguard (is you want a more warrior-like approach) or a wood elf (if you want a more silent-stealth build) or high elf (for mage).
If redguard - use 1handed, light armor (shrouded or nightengale works best) and either sneak or block (stealth or no stealth).
If wood elf - use archery (crossbows if you have DG, nightengale bow, firiniels end (darkbrotherhood kill emperors cousin quest talk to Gabriella) and zephyr (if you have dawnguard), aswell you should use sneak (no pl*ps), light armour (same ones as before) and alchemy.
If high elf - use destruction, conjuration, illusion (really underestimated skill) and perhaps alteration, alchemy or restoration
