Had to a few tweaks to the WP-SEO breadcrumbs. This is what I did.

wp-seo-tweaks.php

<?php
// Remove the last link in breadcrumbs
// WHY? Because it an span tag that contains the title of the page
// But you're already on the page, so what's the point?
add_filter( 'wpseo_breadcrumb_links', 'jj_wpseo_breadcrumb_links' );
function jj_wpseo_breadcrumb_links( $links ) {
	//pk_print( sizeof($links) );

	if( sizeof($links) > 1 ){
		array_pop($links);
	}

	return $links;
}

// Add link to the last item in the breadcrumbs
// WHY? Because, by default, WP-SEO doesn't include the link on the last item
// Since we removed in the function above, we need to add the link back in.
add_filter( 'wpseo_breadcrumb_single_link', 'jj_link_to_last_crumb' , 10, 2); 
function jj_link_to_last_crumb( $output, $crumb){          

	$output = '<a property="v:title" rel="v:url" href="'. $crumb['url']. '" >';
	$output.= $crumb['text'];
	$output.= '</a>';

	return $output;
}

// Add a page to the breadcrumbs of custom taxonomies or post types.
add_filter( 'wpseo_breadcrumb_links', 'my_wpseo_breadcrumb_links' );
function my_wpseo_breadcrumb_links( $links ) {
	global $post;

	// Single pages
	if( $post->post_type == 'custom-post-type' ){ 
		// Add cart page link
		array_splice($links, 1, 0, array(
	array(
	    'text' => get_the_title(34),
			'url' => get_the_permalink(34)
	)
    ));
		return $links;
	}
}

Thanks for code to make the last item as link.
Do you how the change the schema to be with OL LI?
