I like scout/consular characters, usually stopping scout progression at level 4 or 7.
The feats I personally prefer to get are implant lv 3, master dueling, master critical, improved toughness, and improved flurry (because 1 more level of dueling is better than the step from imp to master flurry, and the purple looks better anyway ).
Force powers usually master valor, master speed, heal, force storm, force wave (or only whirlwind if wanting a safe stun on Malak ), if leveled up to consular early enough, force kill and force breach can be fun.
For the attributes, I go for low STR and CON and prefer DEX, INT (RP purposes and helps with HK), WIS and CHA high. For example starting with 10/14/10/14/15/14, stacking 4 of the 5 attribute points one gets into WIS and one into CHA, with full LS mastery and all WIS items + master valor, you get massive dc and have an easy time force-killing even Malak. (5 (base) + 20 (level) + 12 (wis dc) + 6 (cha dc) + 4 (master focus) = 47, quite a force god. ) I usually tend to go somewhere between RPing at the start and number crunching at the end.
