The templated function is the child symbol of the 
TemplateDeclaration which shares the same name i.e

   Dsymbol* s;
   Dsymbol.oneMembers(tempdecl->members, &s, tempdecl->ident);
   auto fd = cast(FuncDeclaration) s;

You then need to visit the templated function parameters « 
(cast(TypeFunction) fd->type)->parameters » and look for 
identifiers that match the TemplateDeclaration.parameters[].ident.

In the simplest cases the types of templated function parameters 
are TypeIdentifier.
