Building on @Jonathon's handler render function, I would just modify the conditions to exclude ValidationException instances.

// If the request wants JSON + exception is not ValidationException
if ($request->wantsJson() && ( ! $exception instanceof ValidationException))

Laravel 5 returns validation errors in JSON already if appropriate.

The full method in App/Exceptions/Handler.php:

/**
 * Render an exception into an HTTP response.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  \Exception  $exception
 * @return \Illuminate\Http\Response
 */
public function render($request, Exception $exception)
{
    // If the request wants JSON + exception is not ValidationException
    if ($request->wantsJson() && ( ! $exception instanceof ValidationException))
    {
        // Define the response
        $response = [
            'errors' => 'Sorry, something went wrong.'
        ];

        // If the app is in debug mode
        if (config('app.debug'))
        {
            // Add the exception class name, message and stack trace to response
            $response['exception'] = get_class($exception); // Reflection might be better here
            $response['message'] = $exception->getMessage();
            $response['trace'] = $exception->getTrace();
        }

        // Default response of 400
        $status = 400;

        // If this exception is an instance of HttpException
        if ($this->isHttpException($exception))
        {
            // Grab the HTTP status code from the Exception
            $status = $exception->getCode();
        }

        // Return a JSON response with the response array and status code
        return response()->json($response, $status);
    }
    return parent::render($request, $exception);
}
