<ul class="pagination"><?php $posts->pagination('words', array(
        'previous' => '<li>« Previous Page · </li>',
        'middle' => '<li>'.$posts->pagination('numbers', false, false).'</li>',
            'next' => '<li> · Next Page »</li>',
            'forceMiddle' => true
        )); ?></ul>

Only issue is, this is what it outputs:

<ul class="pagination">
<li>
<strong>1</strong>
<a title="Go to page 2" href="http://www.site.com.au/blog/page/2/">2</a>
</li>
<a title="Next Page" href="http://www.site.com.au/blog/page/2/">
<li> · Next Page »</li>
</a>
</ul>
