I have all kinds of ideas for pancreatitis.

The food we have Zeus on (and Titan too since she's a bit chubby :D) is Solid Gold Holistique Blendz. It is very low in fat and recommended for pancreatic pups. Then, after a month or so we added in Nature's Variety Raw Chicken and Turkey pre-made medallions. They both love the mix and are doing great on it.
Also, as mentioned before, it is equally important to keep the diet low in sugar as well as fat. Diabetes is another possible side effect of pancreatitis. For treats we give Zeus ice-cubes, apples, carrots, and raw bones (NO marrow, scoop it out - too much protein for the pancreas). We have to go easy on banana's as there is more sugar in citrus fruit.
Okay, hope that helps. I found all of this information out from BW and from my veterinarian so I'm happy to pass along the info.
Also, always mention your pup has pancreatitis when given medication as the organs are more sensitive now. I know Zeus can't take Rimadyl medication for sore joints because of the pancreatitis.
Good luck! Before long you'll be so adjusted you'll forget your "kid" has special needs.
