If it's a modification of an existing gimmick, then I would first think about contacting the originator of that gimmick and ask his permission, unless it's a huge modification.
As for the manufacturing process, that depends entirely on the type of gimmick. i.e. is it a card? plastic? metal?
Also you have to search to make sure that it's not already been created.
I spent years and lots of money developing a gimmicked pack of cards, I thought I had researched it enough, but just before I was due to release it, I accidentally stumbled upon a deck very similar, bang goes my idea! It was there the whole time, just not well marketed.
