@Tornike Choladze's excellent answer led me in the right direction, but in the latest versions of .Net Core (2.0 >) this has to be done a little differently it seems, with regard to the setup.

The custom entity type generator:

class MyEntityTypeGenerator : CSharpEntityTypeGenerator
{
    public MyEntityTypeGenerator(ICSharpUtilities cSharpUtilities) : base(cSharpUtilities) { }

    public override string WriteCode(IEntityType entityType, string @namespace, bool useDataAnnotations)
    {
        string code = base.WriteCode(entityType, @namespace, useDataAnnotations);

        var oldString = "public partial class " + entityType.Name;
        var newString = "public partial class " + entityType.Name + " : EntityBase";

        return code.Replace(oldString, newString);
    }
}

And the setup, which consists of a class in the same assembly and implementing IDesignTimeServices:

public class MyDesignTimeServices : IDesignTimeServices
{
    public void ConfigureDesignTimeServices(IServiceCollection serviceCollection)
    {
        serviceCollection.AddSingleton();            
    }
}
