Any "cookbook" approaches to linear phase EQ?

There are many linear phase EQ plugins out there today with all the standard filter curves (low pass, high pass, bell, shelving, etc.). I assumed there were some RBJ-style "cookbook" filter kernels and methods floating around for this but I can't find any such thing.

So, how is it being done? For example, how does one create a "parametric" bell EQ in linear phase that is user-adjustable on the fly?

I can use a simple "RBJ" filter to do that with IIR - how do you do it with LP FIR?
