Indian Brown from an Extract IPA Kit

Good evening Brewers,

I would like to use an IPA extract kit to make an Indian brown Ale  I have never brewed this style so I am not sure what speciality grains and adjunct to add to be successful.  The kits ingredient list is a bit vague but I am starting with 8lbs of blended syrup, 4 Hops additions 2 of which are aroma and liquid 1056 American Ale from Wyeast Labs. I am a bit new to home brewing and I’ve only brewed straight kit beers in the past, so any advice would be greatly appreciated.
