Your data provider class doesn't necessarily need to be generic - you can just make the AddEntity method itself generic. Then you instantiate a DataProvider instance, and call (for example) its AddEntity method. Your class would look like this:

public class DataProvider
{
    public int AddEntity(TEntity entity)
    {
        using (ITransaction tx = _session.BeginTransaction())
        {
            try
            {
                int newId = (int)_session.Save(entity);
                _session.Flush();
                tx.Commit();
                return newId;
            }
            catch (NHibernate.HibernateException)
            {
                tx.Rollback();
                throw;
            }
        }
    }    
}
