Pagination doesn’t work in custom page template [duplicate]

Try the following and see how you go..

<?php 
  global $paged;
  global $wp_query;
  $temp = $wp_query; 
  $wp_query = null; 
  $wp_query = new WP_Query(); 
  $wp_query->query('posts_per_page=10&post_type=your_post_type'.'&paged='.$paged);
  while ($wp_query->have_posts()) : $wp_query->the_post(); 
?>

<!-- do your loop output here, title, content etc -->

<?php endwhile; ?>

    <?php previous_posts_link('&laquo; Newer') ?>
    <?php next_posts_link('Older &raquo;') ?>

<?php 
  $wp_query = null; 
  $wp_query = $temp; 
?>
