Here's how I solved it. If you are using Laravel 5.5 or above you can override the default exception handler by editing app/Exceptions/Handler.php to add the following:

use Illuminate\Auth\AuthenticationException;

protected function unauthenticated($request, AuthenticationException $exception)
{
    if ($request->expectsJson()) {
        $json = [
            'isAuth'=>false,
            'message' => $exception->getMessage()
        ];
        return response()
            ->json($json, 401);
    }
    $guard = array_get($exception->guards(),0);
    switch ($guard) {
        default:
            $login = 'login';
            break;
    }
    return redirect()->guest(route($login));
}

In the JSON return, you can add any parameters per your requirement.
