Here's a short and concise (I see you guys laughing) list of the most basic and singleminded archetypes for each god, if you want to try them out:
Taurog:
The Taurogzerker - Pick a berserker, prefferably an orc, prep taurog, convert EVERYTHING and kick arse. Well, don't convert getindare, but you can prep extra glyph for more Taurog piety. It's straightforward and an early conversion boost will get you all the Taurog junk and Damage right off the bat. In a simmilar vein, the Taurog Monk is pretty stupid as well.
Mystera - The Goblin Sorcerer. You start with a huge mana pool, so shoot for Mystic balance, a point of Magic, and Refreshment. Then just go nuts with a million fireballs, and time your glyh conversions for either level ups or refreshment. If the boss is magic resistant, get your mana pool up to 18 for 3 fireballs with Magic and mana boosters and spam weakening a bit (spam glyphs while you explore for more piety)
Earthmother - Warlord. Just warlord. Imawal before you fight, fight, plantation for piety and plants, enjoy a bunch of free cydstepps off of clearance. Alternatively search for acid caster - a spellcaster who uses a load of greenblood and explores the map, then levels quickly by killing monsters high above their level whilch lets him reach the end fight with a lot of popcorn, plants, EM piety, plants and corrosion on everything.
TT - The TT Figher. Use slowing effects and Tikki's Edge to up your piety per kill and reach the end fight with a bunch of popocorn for easy mid fight dings and a barrage of fireballs on the boss. You can also grab TT potions to help since scessfully using them doesn't cost you health.
Binlor - The binlor Paladin. It's simple, destroy walls while you explore to get piety and grab all of the permanent damage amplifying boons. Also spam stoneskin for magic resistance and if it is applicable spam it at the end fight, too. It's really straight forward and probably the strongest combo in the game, particularly with the end-game preps/items.
Glowing Guardian - the healthmonster, a dwarf melee fighter, either priest, paladin, or rogue, who converts most of his stuff for health, grabs a few absolutions for more health, grabs humility for even more health, works for enlightment if possible for even more health, and then uses the protection boon to... regenerate a ton of health. You can even keep your health potions and use them if you have the piety, and if the boss is physical resistant, GG has a boon for that too. Fire Heart is a nice prep, and so are the extra attack/health boosters and extra glyph.
Dracul - Either a healthmonster with damage resistances for end game (sanguine lets you regenerate a lot of health, and blood swell is obviously good with lots of health), or a burst piety halfling - convert health potions right away to rush piety gaining boons like lifesteal, sanguine and then just go to town on everything. There's not real set archetype, since many characters can pick Drac up right at the boss fight or even during it just for sanguine or bloodswells.
Jehora Jeheyu - Either a gnome warlord, or a halfling bloodmage - you can get a lot out of raising your health or mana with those two. I'm not an expert but I've used him sucessfuly with a variety of classes, if I found him early.
