Pagination with many to many

Hello,

I'm having issues figuring out how to paginate a many to many relationship. I'm trying to get create a forum app similar to this one here. I attempted to paginate questions asked on a forum with specific tags eg. /discuss/tags/laravel

Question Model:

  public function tags()
   {
        return $this->belongsToMany('App\Tag');
   }

Tag Model:

   public function questions()
    {
        return $this->belongsToMany('App\Question');
    }

Controller:

public function tag($slug)
    {
            $tags = Tag::with('questions.user')->whereName($slug)->paginate(15);
            return view('questions.channel', compact('tags',));
    }

Template:

        @foreach ($tags as $tag)
                @foreach ($tag->questions as $question) 
                     {{$question->title }}
                 {{$question->body }}
                @endforeach
         @endforeach

I can get the proper data to display on my blade template, however can't figure how I would ago about adding pagination to my template. I have tried a few ways but all with errors.
