I'm assuming that DeclaredOnly is too strict a filter.  It's somewhat
non-trivial.  If you use Expression.MemberLookup or
TypeManager.MemberLookup instead of Type.FindMembers, you can use

   mi.DeclaringType != t && mi.IsVirtual && !TypeManager.IsOverride (mi)

to filter out base virtual methods.  However, to ensure that it actually
is overriden, you have to compare the signatures, and/or use
GetBaseDefinition().
