Sparks + Black Robes + One-Handed seems like a cool idea, but I'm curious.

I'll enchant the sword with flames, but what sword do you think would be best to use?

Secondly, what robes are a good idea?

And third, what other magic spells can be used that would seem Sith-like?

dominate skyrim, seek power at any cost, hide you're true nature as you manipulate the population

I'd say wear black robes or vamp armor, use the bound blade, and also electric spells.

Side with the vampires, use the collage for knowledge, serve all daedric lords for the power they bestow, and use the thieves guild and dark brotherhood to corrupt skyrim and give yourself a shadow network of potential spies/assassins

I think illusion, alteration, necromancery/conjuration, and sneak are also really useful skills to consider

Bound Sword

Black Mage Robes

Other lightning spells

Telekenises (the force)

Illusion (Jedi mind tricks)

Why make a Star Wars type character in a Sword & Sorcery fantasy game? Why not be more inventive and lore friendly by going for a D&D type character. At least it'll fit better into the environment. Coincidentally though, recently I've been considering a very similar build for a character http://www.gamesas.com/topic/1462148-an-evil-dracolyte-crusader/#entry22725192. You might like to use some of the ideas for your character. I'll even send you the links to the mods I'd use if you like!

Im running over to the Xbox right now to create a new character based on this. This sounds AWESOME!!!

Since there are no good black cowls, I think the execution masks from the Dark Brotherhood quest would work perfectly. Hooded black robes would work as well, but I'd rather have the two enchant slots with a detached hood.

If you want to be darth vadar use Ebony armour and Deadric/ebony helm

Perfect race for this would be an Imperial. After all, you want to create your Empire.

A Silver Sword would be fitting in terms of length/width. Enchant with Chaos Damage and Fiery Soul Trap.

I think the Nightingale hood might look good for this build.

Get a mod that lets you look like http://images.wikia.com/starwars/images/a/a4/DarthVader-SWG4.jpg. Get a mod to where telekinesis is actually like the force too, it should have been like that to begin with in my opinion.

If only some one could recreate the 'Jedi Powers' mod [Oblivion] for Skyrim. 'Sith Powers' is no longer available.

WOW! Now that's what I call an artist! I had to save that pic, I just had to!

Ha, if only I could take credit for drawing it. I certainly could draw it though.
