Oh wait, I am over thinking this.
Very simple, just "borrow" what bbpress does internally.
<table>
<?php
$tagged_topics = get_tagged_topics(bb_get_tag_id('mixtape'),1,10);
foreach ($tagged_topics as $topic) {
?>
<tr<?php topic_class(); ?>>
<td><?php bb_topic_labels(); ?> <a href="<?php topic_link(); ?>"><?php topic_title(); ?></a><?php topic_page_links(); ?></td>
<td class="num"><?php topic_posts(); ?></td>
<td class="num"><?php topic_last_poster(); ?></td>
<td class="num"><a href="<?php topic_last_post_link(); ?>" title="<?php topic_time(array('format'=>'datetime')); ?>"><?php topic_time(); ?></a></td>
</tr>
<?php } ?>
</table>
Note that bbPress goes by "freshness" by default, meaning when a topic was last replied to. If you want when the topic was created, it will be more tricky.
