Example to use the laravel4-theme package from teepluss Github: https://github.com/teepluss/laravel4-theme

BaseController.php

<?php
//app/controllers/BaseController.php
class BaseController extends Controller {

	/**
	 * Setup the layout used by the controller.
	 *
	 * @return void
	 */
	 
	public function __construct()
    {
        // Using theme as a global.
        $this->theme = Theme::uses('default')->layout('default');
    }

}

PackageController

<?php 

//vendor/<vendorname>/<packagename>/src/controllers/PackageController.php
namespace vendorname\PackageName;

class PackageController extends \BaseController {
	
	public function __construct() {
	
		parent::__construct();
		
	}

	public function index($year = null, $month = null)
	{
		//your code

    //overwrite existing variables in the theme
		$this->theme->set("keywords", "My Custom Meta Keyword");
		$this->theme->set("title", trans('package_name::site.title'));

		
		try {
		  //check the themes and views directory
			$this->theme->scope(\Config::get('package_name::index_view'), $viewData)->location();
			
			//view exists in the theme and/or views directy
			return $this->theme->watch(\Config::get('package_name::index_view'), $viewData)->render();
			
		} catch( \InvalidArgumentException $e ) {
		  
		  //view does not exists in the theme and views directory
		  //we have to use the view from the package directory
		  //this is only a fallback :)
			return $this->theme->load('vendor.vendorname.package_name.src.views.'.\Config::get('package_name::index_view'), $viewData)->render();
		
		}
	}
