For BG1 I pick up the NPCs that were left in Irenicus' dungeon:

Thomas (Paladin)
Minsc (Ranger)
Khalid (Fighter)
Jaheira (Fighter/Druid)
Imoen (Thief, dualed to Mage at level 4)
Dynaheir (Evoker)

Not a bad party, but not the best overall. As mods I use only UB. For BG2 I make these changes:

Thomas (Cavalier) - PC
Anomen (Fighter/Cleric) - decent fighter and good cleric
Minsc (Ranger)
Nalia (Mage/Thief) -> Imoen (Mage/Thief) - since Imoen is missing in the early to middle stages of the game. After I rescue Imoen I ditch Nalia in favour of her.
Viconia (Cleric) - the best cleric ever, combined with Girdle of Stromnos she is killer machine. Beside the romance is very good.

My ToB party looks like this. Can't wait to make UB for ToB. Would love to play an "original" game.

Thomas (Cavalier) - PC
Sarevok (Fighter) - The interaction is awesome in Ascension mod. And by far the best fighter.
Minsc (Ranger) - At late stage of the game is one of the best fighters, best equipped with Two-Handed sword or Halberd.
Viconia (Cleric) - probably the best Cleric in the game. Crom Fayr makes her fantastic. But generally due to low health it is best to equip as a range-attacker.
Imoen (Dual Mage/Thief) - the second best mage after Irenicus and the best thief. I use Ascension mod to boost Imoen's effectiveness in ToB.
Irenicus (Mage) - I use The Longer Road by Dorotea, because I really damn love Irenicus in my party. By far the best mage in the game. Too bad he can't do that spell which he does against the Cowled Wizards.
