Laravel: how to populate a blade SELECT with values from a where statement

I understand you can send values to a select statement like this:

Controller:

$client = Client::lists('name', 'id');
return View::make('index', compact('client'));

And populate this in my view like so:

View:

{{ Form::select('client_id', $client, Input::old('client_id')) }}

But how do I populate only records from Clients where group_id = 1 for example.

I tried:

$client = Client::lists('name', 'id')->where('group_id', 1)->get();

and

$client = Client::lists('name', 'id')->where('group_id','=', 1)->get();

But it doesn't seem to work like that and gives me the error "Call to a member function where() on a non-object"

Any ideas on how to make it work?
