Since I haven't seen your mapping, let me provide mine. You could achieve this by doing like this

public class BaseClassMap:ClassMap
{
    public BaseClassMap()
    {
        /*
         * Identity generator can't be native because subclass objects should be unique
         * So use HiLo or Guid or other generators which will generate unique id on the child tables
         */
        Id(x => x.Id).GeneratedBy.Guid(); 
        Map(x => x.Name);
        UseUnionSubclassForInheritanceMapping(); // This is important - uses union-subclass mappings for the derived classes
    }
}

public class FirstSubClassMap : SubclassMap
{
    public FirstSubClassMap()
    {
        Table("FirstSubClassTable");
        // Map properties for FirstSubClass
    }
}

public class SecondSubClassMap : SubclassMap
{
    public SecondSubClassMap()
    {
        Table("SecondSubClassTable");
        // Map properties for SecondSubClass
    }
}
