Remember,these are all just suggestions!
Here is a build I would recommend,but,being no expert on wizards,you may have a lot to improve on it(I am using APG):
STATS:
Str 8 =Affects carrying capacity.
Dex 16(14+2) = Affects to-hit bonuses with ranged weapons and ranged touch attacks.Also affects your AC.
Con 12(14-2) = Affects your HP.You can't do anything if you're dead,though you could lower this in order to get a higher Dex.
Int 21 =Affects what spells you can cast and the DCs for them.Raise at 4th level.
Wis 9 = Affects your Will saves.You can keep it here or raise it at 4th/8th if you want.
Cha 7 =Affects your social skills.You're not a bard/paladin/whatever Cha caster you think of.
FEATS:
L1:Toughness.D6 HP and a 12 Con? You need it.
L1(Wizard Bonus):Scribe Scroll.It's automatic,so you'll take it.
L3:Improved Initiative.This is great for God wizards.
L5:Augment Summoning.Your summoned creatures need all the help they can get!
L5(Wizard Bonus):Extend Spell Metamagic Feat.Double the duration for an extra level is great;use it on spells like Grease or buffers.
CLASS FEATURES:
Arcane Bond:Take a familiar every time.If the bonded object gets destroyed,you're kinda screwed.Familiars I suggest are either the Raven(Scouts ahead),Toad(Extra HP!)Rat(Fort bonus),or the Compsognathugas(Mini dino that grants big initiative bonus).
Arcane School:Pick conjuration-having an extra ally is always great.Only use Acid Dart if you run out of spells.Take Enchantment and either Abjuration or Divination as your opposed schools.
Bonus Feat:Choose Extend Spell at 5th level.
GEAR
If you want to,grab a Quickdraw Shield and mithril it.Then,save up for a Headband of as much Int as you can get.
