Look Teleport: Particle System

I made a teleport script so that when you click you teleport to the object your looking at, but I want to make a particle system kind of like the orbital strike from battle front where there is a circle that follows where you look and can tell you where you're going to teleport.

using UnityEngine; using System.Collections;

public class LookTele : MonoBehaviour {

 private RaycastHit lastRaycastHit;
 public AudioClip audioClip;

 // Use this for initialization
 void Start () {
     Cursor.visible = false;
 }

 private GameObject GetLookedAtObject(){
     Vector3 origin = transform.position;
     Vector3 direction = Camera.main.transform.forward;
     float range = 1000;
     if (Physics.Raycast (origin, direction, out lastRaycastHit, range))
         return lastRaycastHit.collider.gameObject;
     else
         return null;
 }

 private void TeleportToLookAt(){ 
     transform.position = lastRaycastHit.point + lastRaycastHit.normal * 2;
     if (audioClip != null)
         AudioSource.PlayClipAtPoint (audioClip, transform.position);
 }
     // Update is called once per frame
 void Update () 
 {
 if (Input.GetButtonDown ("Fire1"))
         if (GetLookedAtObject  () != null)
             TeleportToLookAt ();
 }

}

any help is great.
