custom post type page template pagination

I am trying to make a page template for the latest custom post types and it shows the recent 10 posts but i want to add a pagination at the end of it!
it is not the archive page it is a custom page template.

<?php
global $wp_query;

$wp_query = new WP_Query("post_type=questions&post_status=publish&posts_per_page=10");
if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<div style="margin:10px;padding:5px;border-bottom:1px dashed #ebebeb;height:auto;">
<div style="float:right;width:60px;margin-left:10px;" class="questions-page-2">
<?php echo get_avatar( get_the_author_email(), '48' ); ?>
</div>
<div style="float:left;width:450px;" class="questions-page-1">
<h6 class="toggle"><a href="#" style="opacity: 1;"><?php the_title(); ?></a></h6>

<div class="toggle_content" style="display: block;">
<div class="block"><?php $content = get_the_excerpt();
echo substr($content, 0, 120); ?> <a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>">... show question</a>
</div>

</div>
</div>
<div class="clearboth"></div>
</div>
<?php endwhile;
endif; ?>
