Solution 1

You can do that by applying Storyboard on Click event trigger:

<ControlTemplate TargetType="HyperlinkButton">
   <StackPanel Orientation="Horizontal"  Background="#EBEBEB" x:Name="sp1">
      <Image Source="/Assets/Menu/wheretostay.png"  Stretch="None"/>
      <TextBlock />
   </StackPanel>
   <ControlTemplate.Triggers>
     <EventTrigger RoutedEvent="ButtonBase.Click">
        <BeginStoryboard>
          <Storyboard>
            <ColorAnimation To="Green" Storyboard.TargetName="sp1" 
                            Storyboard.TargetProperty="Background.Color"/>
          </Storyboard>
        </BeginStoryboard>
     </EventTrigger>
   </ControlTemplate.Triggers>
 </ControlTemplate>

For Windows Phone 7, use Visual State:

<ControlTemplate TargetType="HyperlinkButton">
   <ControlTemplate.Resources>
     <SolidColorBrush x:Key="PhoneBackgrounBrush" Color="Green"/>
   </ControlTemplate.Resources>
   <StackPanel Orientation="Horizontal" x:Name="sp1">
      <VisualStateManager.VisualStateGroups>
         <VisualStateGroup x:Name="CommonStates">
            <VisualState x:Name="Normal"/>
            <VisualState x:Name="MouseOver"/>
            <VisualState x:Name="Pressed">
               <Storyboard>
                 <ObjectAnimationUsingKeyFrames
                         Storyboard.TargetProperty="Background"
                         Storyboard.TargetName="sp1">
                    <DiscreteObjectKeyFrame KeyTime="0"
                            Value="{StaticResource PhoneBackgrounBrush}"/>
                 </ObjectAnimationUsingKeyFrames>
               </Storyboard>
            </VisualState>
         </VisualStateGroup>
       </VisualStateManager.VisualStateGroups>
       <Image Source="/Assets/Menu/wheretostay.png" Stretch="None"/>
       <TextBlock />
   </StackPanel>
 </ControlTemplate>

Solution 2

Try this

use this name space using System.Windows.Media; and in button click event write this

private void WhereToStayButton_Click(object sender, RoutedEventArgs e)
{
   stackpanelname.Background = new SolidColorBrush(Colors.Red);
}

You can use VisualStates in Windows Phone 7 like described here. Create Pressed Visual state.

I have updated the answer for Windows Phone 7. Have a look at it.

Good it works i have to change to original background color when button click is completed.

[Rohit Vats]

In case you want to revert back to original value. Simply add two more Visual States for Normal and MouseOver. I have updated in answer.
