wordpress plugin using class functions problem

So this is my first time making a plugin using basic OOP principles. My plugin basically looks something like this at the moment:

/*
plugin info
*/
class plugin_name {
      public function __construct() {
            //this is repeated for a whole mess of other functions and I'm not sure what hooks to put them on (they are made up of api calls and basically functions with markup in them)
           add_action('wp_enqueue_scripts', array($this, 'scripts')
      }

     public function mark_up_function1() {
        ..........................
        ..........................
     }
}
$mm_stock_info = new mm_stock_info();

Then on a template page I call the markup functions like so

$mm_stock_info->mark_up_function();

when I try to load the page that is utilizing this plugin the most I get a mostly blank screen (but my css and js is loading onto the page). Does anyone have any suggestions to what my problem may be?

This worked...

/*
plugin info
*/
class plugin_name {
      public function __construct() {
            //this is repeated for a whole mess of other functions and I'm not sure what hooks to put them on (they are made up of api calls and basically functions with markup in them)
           $this->register_callbacks() 
      }

     protected function register_callbacks() {
     add_action('mark_up_function1', array($this, 'mark_up_function1'));
     }

     public function mark_up_function1() {
        ..........................
        ..........................
     }
}
$mm_stock_info = new mm_stock_info();

Then in the theme something call the function with the hook you called in the plugin

do_action('mark_up_function1');

Is the function being called correctly? It looks like you've created a function called mark_up_function1 but you're calling a function called mark_up_function.

That was a typo on my part (was trying to write up a quick example) but in the actual code the function is the correct name.

What hooks do you recommend I use for these functions that make an API call and present it in HTML form?

Sorry can't help you there. Haven't really dug in to the plug-ins end of Wordpress yet.
