First,
here is a link to the D20PFSRD's list of golems. There's at least two dozen, so you might get a lot of inspiration from that.
I would probably create a Golem-Master with Projection and Variable Abilities. The Variable Abilities has several lists, one for each type of golem you want to create. Add Ritual:Golems for less direct-combat stuff (i.e. making a bird-shaped golem to go spy on someone), and it'd probably look something like this, at no specific power level.
Ritual: Golems [-2]
Refinement [-X]
Skilled Projection [-3]
Variable Abilities (Golem Master, -3 Surcharge) [-X]
Limitation [+X] Variable Abilities only apply to golems.
An Iron Golem's list, for example, would probably look a bit like this. The building blocks would vary depending on your power level, and the specifics of the golem. An animated suit of armor is going to have different stats than something the size of Optimus Prime. (For reference, I based this on the Pathfinder version of an Iron Golem.)
Inhuman Strength [-2]
Supernatural Toughness [-4]
Supernatural Recovery [-4]
Immunity (Mortal Magic, Fire) [-6]
Limitation [+7] Toughness and Magic Immunity bypassed by rust and electricity attacks, Golem takes -2 penalty to all Athletics rolls and cannot take supplemental actions for two rounds after being hit by an electricity attack, Recovery activates only after being hit by a fire-based attack.
Hulking Size [-2]
Ranged Area Venomous Natural Weaponry (Sword, Poison Gas) [-4]
Semi-Animate [-1]
Mindless [-0]
Feel No Pain [-3]
Oh, and regarding flavor stuff for Golems, it depends on if you want to do historical/mythic golems (big clay dude with the name of God written on his forehead, keeps him alive) or more modern golems, which suit the DFRPG's definition of a golem better (a big hunk of mortal-world-stuff with an animating spirit, typically an elemental, caged inside of it and keeping it animated. the barrier that keeps the elemental
in has the additional effect of keeping all other magic
out. The mythical Golem has more of a "holy" bent to him, while the modern ones are a bit more multipurpose. Golems can be pretty versatile depending on how esoteric you're willing to get with it. Iron Golems, to use the above example, are typically big suits of armor, which is fine. However, don't think "animated armor". Think about those big metal eagles on the side of the Chrysler building. Think about a gigantic, poison-ink-breathing metal kraken that you reshaped a submarine into. Think about Iron Man. Think about Pacific Rim.
Well, that was my two-cents.
