Yeah, Erastil with domains Feather (for sure) and Growth (maybe) might work. Keeping the above traits. Feather gets you an animal companion at 4th level like a ranger, boon companion at that time will bring it up to full HD. It also gets you Eyes of the Hawk, a racial bonus to perception = half your character level, and a +2 to initiative if you can act in a surprise round. Plus you get Fly as a 3rd level spell, Fly becomes a class skill, and whenever you get a fly speed your maneuverability goes up by 1 step. Growth gets you Enlarge self for 1 round as a swift action, and adds Enlarge Person to your list of class spells. There may be better options for the 2nd domain, but this one is pretty good for your dwarf.
Work out your stats so Dex>Wis,Str>Con,Int>Cha. With racial bonus, could be 16/14/14/13/12/10 as Human, with the +1 at 4th going to Con, the +1 at 8th going to Wis. You could even get away with starting Wis at 13 and Con at 14 for the extra hp and fort save early, and putting both the 4th and 8th level points into Wis. Either way you're not going to focus on spell DC's, let your wizard render your foes useless while you buff, support, and heal afterwards. Be a switch hitter with an adaptive composite longbow +1 (cost you 3450gp if my maths are right) and the +2 heavy flail. Little trick have a pack animal standing next to you with large arrows, when you enlarge yourself, draw a large arrow from the pack animal's quiver, now you're -2 to attack but your arrows do 2d6+4 instead of 1d8+3. Get a mithral chain shirt for 1100gp and plan on adding bonuses to it. As you go, get +2 to dex first, then +2 to wis, etc.
Feats will be tricky, and up to you. If you want to be a switch hitter (and in a 3 man party you kind of have to be) you can't just focus on archery feats. You'll want Point Blank shot and Power Attack, then Precise shot and Boon Companion probably. Or a Skill focus feat in perception or survival, just use the bow when the dwarf isn't yet in melee. Going full into archery is expensive, since you really need 4 feats ASAP (PBS, PS, DA, RS), and the Cleric doesn't give you that unless you specialize.
Edit: you could just stick with Animal domain instead of Feather. You give up fly as a class skill in exchange for Know (nature), you lose the fly spell, and you lose the bonus to Perception in exchange for Speak with Animals 3+Wis times per day. I like Feather a lot more than Animal, but flying around isn't necessary for a scout, while speaking with animals and know (nature) might be appropriate.
