I had to think about this for a little bit because I usually shy away from smoked apps if the meal will be smoked meats. Also, folks in Cali-forn-i-a don't eat like regular folks. You hardly ever see them eatin' a mess of chittlin's or fried squirrel, so it took some thinking on my part.
I second or third the ABT's and chicken wings, but I don't have the patience for making 90 ABT's. Here are some things you could try that are kinda sorta smoked, but all are easy and do ahead type things so you can properly attend to the beer drinking.
Brushetta anything! Get some fancy sausage that you left coasters are so fond of(chicken/asiago cheese, chicken/spinach, something spicy, etc) then smoke it and grind in food processor with cream cheese(and a little mayo/sour cream to thin), and serve on toast. Do 2-3 kinds, adding caramelized onions, roasted red pepper, etc. and then just have lots of toast which can be made a day ahead and re-toasted in an oven for a couple of minutes to freshen up.
Same as above except for grilled/smoked veggies. Eggplant dip with tahini, roasted rep pepper hummus. Do a smoked tomato and onion sauce. Just a smoked tom and an onion, then process with mayo. S&P to taste. Like a smokey 1000 island dressing but goes well with most anything on toast.
Same as above but smoked salmon with dill dream cheese and capers, maybe some diced red onion.
Spring rolls(cold type) with smoked pork, smoked shrimp, or both with peanut sauce or spicy duck sauce. (rice wrappers, basil leaves, cilantro, mint leaves, cellophane noodles, shredded carrots, bean sprouts, meat)
Pulled pork in wonton wrappers, fried. (little BBQ egg rolls) Served with spicy vinegar based slaw and BBQ sauce of choice.
Smoked chicken, chopped with soy sauce and toasted sesame oil, scallions, water chestnuts, shredded carrots, and cellophane noodles in lettuce cups. Pretty much the same as the spring rolls. Be careful with the sesame oil if you haven't used it before. A little goes a long ways. Put this out on a tray and let people make their own.
Smoked pork tenderloin, marinated with hosin sauce or glazed with same at end of cooking, rolled in toasted sesame seeds, then chilled and sliced thin. Served with peanut dipping sauce.
Grilled ahi tuna with wasabi sauce, or smoked in a dip with wasabi and cream cheese on sesame crackers.
All this sounds good and all, but if you can get some frog legs, turtle meat, or swamp rat we could really make this a party to remember.
